the position of the Cossack force was likely to put
to hazard the future advances of the Kalmucks, or at
least to retard and hold them in check until the heavier
columns of the Russian army should arrive upon their
flanks. The siege of Koulagina was instantly raised;
and that signal, so fatal to the happiness of the women
and their children, once again resounded through the
tents--the signal for flight, and this time for a flight
more rapid than ever. About 150 miles ahead of their 5
present position, there arose a tract of hilly country,
forming a sort of margin to the vast, sealike expanse of
champaign savannas, steppes, and occasionally of sandy
deserts, which stretched away on each side of this margin
both eastwards and westwards. Pretty nearly in the 10
centre of this hilly range lay a narrow defile, through
which passed the nearest and the most practicable route
to the River Torgau (the farther bank of which river
offered the next great station of security for a general
halt). It was the more essential to gain this pass before 15
the Cossacks, inasmuch as not only would the delay in
forcing the pass give time to the Russian pursuing
columns for combining their attacks and for bringing
up their artillery, but also because (even if all enemies in
pursuit were thrown out of the question) it was held, by 20
those best acquainted with the difficult and obscure geography
of these pathless steppes--that the loss of this one
narrow strait amongst the hills would have the effect of
throwing them (as their only alternative in a case where
so wide a sweep of pasturage was required) upon a circuit 25
of at least 500 miles extra; besides that, after all, this
